The density of pure titanium at room temperature is approximately 4.51 g/cm³ (4510 kg/m³; 0.163 lbm/in³). For context across materials, see the Density of Materials hub and the comparative Density of Metals chart. Titanium alloys offer high strength‑to‑weight ratio with modest density changes depending on alloy content and phase (α, β, or α‑β).
